# print.power.htest

##### Print Methods for Hypothesis Tests and Power Calculation Objects

Printing objects of class `"htest"`

or `"power.htest"`

,
respectively, by simple `print`

methods.

- Keywords
- htest

##### Usage

```
# S3 method for htest
print(x, digits = getOption("digits"), prefix = "\t", …)
```# S3 method for power.htest
print(x, digits = getOption("digits"), …)

##### Arguments

- x
object of class

`"htest"`

or`"power.htest"`

.- digits
number of significant digits to be used.

- prefix
string, passed to

`strwrap`

for displaying the`method`

component of the`htest`

object.- …
further arguments to be passed to or from methods.

##### Details

Both `print`

methods traditionally have not obeyed the
`digits`

argument properly. They now do, the `htest`

method mostly in expressions like `max(1, digits - 2)`

.

A `power.htest`

object is just a named list of numbers and
character strings, supplemented with `method`

and `note`

elements. The `method`

is displayed as a title, the `note`

as a footnote, and the remaining elements are given in an aligned
‘name = value’ format.

##### Value

the argument `x`

, invisibly, as for all `print`

methods.

##### Examples

`library(stats)`

```
# NOT RUN {
(ptt <- power.t.test(n = 20, delta = 1))
print(ptt, digits = 4) # using less digits than default
print(ptt, digits = 12) # using more " " "
# }
```
